Tax Cuts and Jobs Act (TCJA): A congressional revenue act originally introduced in Congress that amended the Internal Revenue Code of 1986. Major elements of the changes include reducing tax rates for businesses and individuals; a personal tax simplification by increasing the standard deduction and family tax credits, but eliminating personal exemptions and making it less beneficial to itemize deductions; limiting deductions for state and local income taxes (SALT) and property taxes; further limiting the mortgage interest deduction; reducing the alternative minimum tax for individuals and eliminating it for corporations; reducing the number of estates impacted by the estate tax; and repealing the individual mandate of the Affordable Care Act (ACA).
